'VA'PORIZER OR; CARBURETER FOR GKS-ENGINES- specifieation of Letters Patent.

Patented March 17, 1908.

l Application led June 22, 19071 Serial No. 380,348.

To all whom it 'may concern:

Be it known that I, CHARLES D. SHMN, a

and State of New York, have invented a certain new and useful Vaporizer or Carburetor for `Gras-Engines.

'My invent-ion relates to im fly valve, commonly used as a throttle for controlling the quantity of gas passing to the en ine; isalso used for regulating the quanftit of auxiliary air ta` en into the carburet-erfand lthe objects of' my invention are, first, lto provide auxiliary air ports, which may he supplied with either heatedor cold air, so Constructed that in opening or partly opeping the buttery valve throttle, the au' ports will be .opened or partly opened and in closing' or partly closing the butterfly valve throttle, vthe air ports will be-closed or partly closed. l attain these objects by the mechanism illustrated in the accompanying drawings, in. which 2'-` Figure' 1, is a vertical section of the vaporizer -or carburetor with' the coupling and suction air valve removed; Fig.. 2, is a bot- 'tom Vview of the carburetor; Fig. 3, is a vertical view of a partly hollow plug containin a screen and bushing; Fig. 4, is a sectiona v view of a shaft, cam and milled nut looking plug' from right to left; Fig. 5,-is a section of the upper-part. of one of the auxiliary air tubes;

Flg. 6is a sectional view showing a coupling andsuction air valve. The. arrows at the bottom show the air-inlets and the arrowjat thetop the gas-outlet to engine.

Similar letters refer to similar parts throu hout the drawing.

In 'g. 1, V is a float cup for gasolene or liqluid uel, containing a float U, with ball va veneer the top, ofthe usual construction. The gasolene orliquid fuel enters the cup at M arid-leaves atZ Zand passes through the pipe Y and flows into' the chamber T. In thls chamber T, isv inserted a partly hollow K, with a screw thread at the bottom of.1t,and"arou`nd a part of the plug K is placed la. screen S for screenin Jthe gasolene or liquld fuel. In the top of t e plug K is a has=a oie in fthe' center ot it, the'size of. WhiclNSZdetermined by the maximumflow of gasolene oi" liquid Iu'el 4required for afspe-` fuel afterentering the chamber.T,.l,pasees= TheA bushing L,

through the.- screen JS, into the hollow .art of the plug K and from there it is suc` ed by the engine or forced-by the pressurebehind it, through the bushing'L, into the tube D, where its flow is in a measure arrester-l by the ball valve or'sprayerA. The'lift ot the t ball valve or sprayer A, is caused: by suction rovements 1n.4 vaporlzers or carbureters 1n w ich a butter.

ofthe shaft E (Fig 4'). T he shaftE amlthel .cam H, areturned by themilled nut I, which isheld in any Vfixed position desired, by the ball spring (9:

a, a, are a number of air ports extending.'

from the bottom of the vaporizer or carbuL reter, (see Fig. 2) upto the mlxing chamber X. These ports are for the purposes of furnishing th'e'fixed air supply while others a c and` c5 a5 are used forthe auxiliary air sup ly and c a. are tapped andthreadedwhere t ley enter the mixin chamber X and into lthem are inserted. small tubes threaded at the bottonft a a/, (see Fig. 5). slots in their sides at, from which the auxiliary air issues. These tubes a are covered by ca s c2, (see Fig. 5). Between the caps a? an the bottom of the mixing chamber X, are springs c3, coiled around the tubes a. and when the butterfly valve N is open or partly open, the springs c3 and the suction from the engine lthrough C, raisethe ca s as, so that the, slots a, are open or party open; and whenv the buttery -valve N, is lclosed or partly closed,` it pushes down the caps a,24

over the slots a? in the tubes c thereby closing or partly closing them. The springs a? are astene to the ca s a2 and also to the bottom of the mixing c amber X, to prevent the caps from` leaving the tubes a by the suction of the engine. The caps a2 may also have pins .on the inside, fitting into the slots a, for the same urpose. The butterfly valve'N, isoperate by the shaft b and the lever-P (Fig. 1). The gasolene or'liquid fuel after bein mixed with air in the mixing chamber passes, out of the vaporizer or carbureter at C. i

The bottom of the vaporizer or carbureter is threaded at R, to receive a union F G with heated' air; or the openings leadin tol (Figs. 1 and o) with a commonly used suction air valve J Q; and these may be connected to "the auxiliary air tubes a may -be plugg at the bottom of the vaporizer orA carbureter and tubes run through the side of the vapo-l float U, in connection with a vaporizer or carbureter, forms no part of my invention.

What l do claim as my invention, and desire to's'ecure by Letters Patent isz;

The combination in a vaporizer or carbureter-of a butteriiy valve, a casing forming a mixing chamber, provided With main and auxiliary air passages, extending vertically ,through 'the lower Wall of the casing; additional auxiliary air passages extending horizontally from the nrst mentioned auxiliary air passages through the casing of the carbu-` reter, the first mentioned auxiliary air passages directly opened partly or fully, or closed partly or fully, by the butterfly valve and arranged so their air supply from the bottom of the carbureter or vaporizer, can be cut oit and these auxiliary passages supplied With air separately if desired, by means of the air passages extending from these vertical air passages, horizontally, to the outside of eeaeae the vaporizer or carbureter; Awith a plain union containing a suction air valve at the bottom of the vaporizer or carbureter, for supplying either'heated or cold air and a ball valve or sprayer located in the mixing chamber and seated in a support, and a passage through the support for the delivery of gasolene yor liquid fuel under the ball, into the mixing chamber, the ball valve controlling this delivery; an eccentric cam on a shaft, a milled nut .on one end of the shaft, and a ball spring, extending from the' carbureter casing and contacting With the milled nut, the cam and shaft being .located above the ball and operated by the milled nut, Which is `held in any desired position by the bali spring; and

a partly hollow screened plug. and bushing fior the passage of gasolene or liquid fuel, through the said support into the mixing chamber; the partly'hollow blug having in its top a bushing with a hole through its oenter, the proper size orsupplying' the maximum iioW of gasolene or lliquid fuel required for any speciiic size of engine, all substantially` asset forth.

Witness my hand this twenty-'first day of June, 1907,' at the city of New York, in the county and State of New Yorlr.`
